Not everyone can afford a brand-new Toyota Prius. But don't fret--if you can afford a 1987 Honda CRX, you too can join the green revolution!

With gas prices soaring and most hybrid vehicles still unaffordable, a growing number of drivers are flocking to fuel-efficient old clunkers to save money. And for good reason.

Try this on for size: the 1987 Honda Civic CRX gets an astonishingly-efficient 57 miles per gallon on the highway. Yes, seriously! Not even the Toyota Prius, a hybrid vehicle, can come close to that.

Sure it only has 62 horsepower and two seats, but it has a sporty look and plenty of legroom. And with plenty still cruising the roadways today, they were extremely well-built. On top of that, it draws a near-perfect score in greenhouse gas emissions from FuelEconomy.gov. Great gas mileage, environmentally-friendly and affordable--how can you go wrong?

Another fuel-efficient beacon of yesteryear is the 1994 Geo Metro. It isn't very stylish, and its 0-60 time is just over three-and-a-half hours, but getting nearly 60 miles per gallon on the highway is all the style most folks need.

Before you tear off to the local junkyard, though, keep something in mind: it's a Geo Metro. Getting behind the wheel of this sardine can is like taking your life in your hands. If you're comfortable driving a car that has less interior space than an airplane restroom, this one's for you. Can you believe a '93 Metro with 22,000 miles sold for over $7k in a recent online auction?

Here are some other junkers that might be worth digging up:

1982 Chevy Chevette: 40 mpg city, 55 mpg highway

1983 Volkswagen Rabbit: 48 city, 61 highway

1984 Ford Escort: 46 city, 68 highway

1984 Nissan Sentra: 50 city, 66 highway

1985 Suzuki SA310: 47 city, 53 highway

1986 Chevy Sprint ER: 55 city, 60 highway

1994 Geo Metro: 53 city, 58 highway
